I have had 3 sets of trijicons on my Sigs, when it came time to night sight the 245, they were out of stock for the trijs at my local gun shop. Instead he showed me the MeproLights. I looked at em for a sec and bought them...

Now, I'm a believer... they have a larger surround than the trijs so they work better in bright lit conditions. As far as night illum goes, they seem brighter, but to be fair the newest set of trijs I have to compare them to are already 5 years old.
